1)  Imagine you are a part of a big orchard with a lot of trees around. How do you feel being cut?
-If I are part of a big orchard with a lot trees around, I felt very sad if I being cut. At first I felt very fortunate because I give protection to people and animals to shelter . I felt very sad. I cannot talk does not mean I cannot feel. I wonder, do they feel what I feel? I was disappointed because they are selfish and they do not think what the effect of the deforestation.

2) What will happen to all the animals which were talking shelter on you?
-Animal which were talking shelter on me are be effected.Forests are natural habitats to many types of animals and organisms. That is why, when there is deforestation, many animals are left without shelters. Those that manage to go through the flat lands and residential sites are then killed by people.
Through the years, it is estimated that there are millions of plant and extinct animal species that have been wiped out because they have been deprived of home. Thus, biodiversity is significantly lowered because of the savage deforestation practices of some people.
Wildlife advocates have been constantly reminding that several wild animals left in the world could still be saved if deforested forests would only be reforested and the practice of slash and burn of forests would be totally abandoned.

3) What would be the surroundings like after you are cut?
-The surrounding will effect by the change in temperatures in the nearby areas. Forests naturally cool down because they help retain moisture in the air.
-Second is the long process of global climate change. As mentioned above, deforestation has been found to contribute to global warming or that process when climates around the world become warmer as more harmful rays of the sun comes in through the atmosphere.
-The ozone layer is a mass of oxygen or O3 atoms that serves as shield in the atmosphere against the harmful ultraviolet rays from the sun. Because ozone is made up of oxygen atoms, oxygen react with carbon monoxide. Such reaction would use up oxygen atoms.
-It follows that when there are more carbon monoxide atoms going to the atmosphere, the volume of oxygen would decline. Such is the case of ozone depletion.
-The third effect to the environment would be on the water table underneath the ground. Water table is the common source of natural drinking water by people living around forests.
-Water table is replenishing. That means, the supply of water underground could also dry up if not replenished regularly. When there is rain, forests hold much of the rainfall to the soil through their roots.

-Thus, water sinks in deeper to the ground, and eventually replenishing the supply of water in the water table. Now, imagine what happens when there is not enough forests anymore. Water from rain would simply flow through the soil surface and not be retained by the soil.
-Or other than that, the water from rain would not stay in the soil longer, for the process of evaporation would immediately set in. Thus, the water table is not replenished, leading to drying up of wells.

4) What change will take place in the environment after you are cut?

The change will take place in the environment after cut is:-

Erosion of Soil: When forest areas are cleared, it results in exposing the soil to the sun, making it very dry and eventually, infertile, due to volatile nutrients such as nitrogen being lost. In addition, when there is rainfall, it washes away the rest of the nutrients, which flow with the rainwater into waterways. Because of this, merely replanting trees may not help in solving the problems caused by deforestation, for by the time the trees mature, the soil will be totally devoid of essential nutrients. Ultimately, cultivation in this land will also become impossible, resulting in the land becoming useless. Large tracts of land will be rendered permanently impoverished due to soil erosion.

Disruption of the Water Cycle: Trees contribute in a large way in maintaining the water cycle. They draw up water via their roots, which is then released into the atmosphere. A large part of the water that circulates in the ecosystem of rainforests, for instance, remains inside the plants. When these trees are cut down it results in the climate getting drier in that area.

Loss of Biodiversity: The unique biodiversity of various geographical areas is being lost on a scale that is quite unprecedented. Even though tropical rainforests make up just 6 percent of the surface area of the Earth, about 80-90 percent of the entire species of the world exist here. Due to massive deforestation, about 50 to 100 species of animals are being lost each day. The outcome of which is the extinction of animals and plants on a massive scale.

Flooding and Drought: One of the vital functions of forests is to absorb and store great amounts of water quickly when there are heavy rains. When forests are cut down, this regulation of the flow of water is disrupted, which leads to alternating periods of flood and then drought in the affected area.

Climate Change: It is well known that global warming is being caused largely due to emissions of greenhouse gases like carbon dioxide into the atmosphere. However, what is not known quite as well is that deforestation has a direction association with carbon dioxide emissions into the atmosphere. Trees act as a major storage depot for carbon, since they absorb carbon dioxide from the atmosphere, which is then used to produce carbohydrates, fats, and proteins that make up trees. When deforestation occurs, many of the trees are burnt or they are allowed to rot, which results in releasing the carbon that is stored in them as carbon dioxide. This, in turn, leads to greater concentrations of carbon dioxide in the atmosphere.

5) Message you would like to give to people who are cutting down trees.
Message that I would give to people who are cutting down trees is stop destroying the forests, which are so valuable to us. The forests are a boon to the earth which is bestowed with different natural resources. Extensive deforestation means the increase in pollution, global warming, natural calamities like flood and drought. Furthermore,they should stop to cutting of the tropical forests . Because rebirth of certain new species which would help in the balance of the flora and fauna. There are certain steps to be taken in order to keep the beauty of the nature intact
The people must be provided with certain knowledge about the ecosystem of the earth so that the people know the importance of the trees and stop the illegal cutting of the trees. There should be certain programs so that the children can teach their elders how important the trees are for the earths existence. The children must be taught the importance of the trees because the children of today are the future of tomorrow. Education should not however stop only amongst the school aged children but should be continued to the upper level i.e. the older people should also be taught the preventive measures of deforestation. The education however has become the easiest way to transfer the message. Saving the forests is a worldwide duty of the people. Measures should be taken by the people to save and preserve the forests.
To save the forests, eco-tourism should also be encouraged so that the people feel that forests are important for attracting the tourists to their country.

6) What do you think the use of technology in reducing and minimizing the problem?

I think the use of technology in reducing and minimizing the problem can improve solution of deforestation. For example, recycling benefits to the environment. With recycling, we can get saves trees. As a mentioned earlier, recycling a single ton of paper can save almost 17 trees from cutting of. Deforestation is a major cause of concern globally. Also, issues like soil erosion, acid rain, global warming, etc are directly or indirectly related to it. Therefore, the more you recycle, the more you contribute in making the earth greener.
After that, we also can saves the energy. Did you know that by recycling 1 glass bottle we can save energy that would be sufficient enough to light a bulb for 4 hours! Production of some materials consumes more energy, than recycling the same materials. For example, cutting out trees to create new paper would take more time and energy as compared to recycling paper. The same is the case with steel which takes a lot of energy in manufacturing as compared to recycling.After than that, increasing productivity of cleared rainforest lands is possible using improved technology to generate higher yielding crops.
- Taking advantage of improved germplasm developed through careful selection can produce grasses and crops that will grow on degraded forest soils. While technology may have accelerated the development and impoverishment of tropical rainforests, it will be one of the keys to saving them.

7) In your opinion, blog is able to stimulate environmental awareness among community. Elaborate.

In my opinion, blog is able to stimulate environmental awareness among community:-
  -Blogger who blog can arrange a meeting to discuss a problem that bloggers have a strong influence. For example, discusses the deforestation problem.
  -Blog as a medium advertising.
  -Blog also to some extent to bring awareness to society of environmental damage.
  -Through blog, we can organize a campaign to save our forest as well to give a message to the community.
